Connection to the mains must be made through a disconnecting
device, which is integrated into the fixed wiring system in accordance
with the wiring rules for design of electrical units, and has a contact
separation in all poles that allows for full disconnection under
overvoltage category III conditions.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent, or similarly qualified persons in order
to avoid a safety hazard.
Ensure that the unit is switched off from the supply mains before
removing the guard.
Precautions must be taken to avoid the back-flow of gases into the
room from the open flue of gas or other fuel-burning appliances.
The appliance may adversely affect the safe operation of appliances
burning gas or other fuels (including those in other rooms) due to
back flow of combustion gases. These gases can potentially result
in carbon monoxide poisoning. After installation of the unit the
operation of flued gas appliances should be tested by a competent
person to ensure that back flow of combustion gases does not occur.

The diameter of the spigots in the Stream 100/125 model can be changed using adapters, and in the Stream 150/160 model
using the rubber seal.
On outlet (discharge) spigot side it is necessary to install:
• in case of horizontal installation – a duct with a length of at least 1 m;
• in case of vertical installation – a canopy preventing moisture from getting into the fan.
The outlet spigot must always be connected to the air duct.

ELECTRONICS OPERATION ALGORITHM
Stream...P Stream...U, Un
Stream
The fan speed without options can be controlled by voltage, as well as by thyristor controllers.
A speed controller can be purchased separately.
Warning! When adjusting the voltage, ensure that there is no unusual noise or vibration at reduced motor speed.
When adjusting the voltage, the motor current may exceed the rated current.
The fan is equipped with a thermal switch without self-reset.
Probable causes of the thermal switch tripping:
• non-compliance with the operating rules
• impeller jamming (clean the impeller)
• motor malfunction (turn off the unit, contact the Seller)
To reset the thermostat:
• Switch off the power supply.
• Find and eliminate the cause of overheating.
• Switch the power back on.

The Stream ...T fan activates upon control voltage application to the LT input terminal by the external switch (e.g. indoor
light switch). After the control voltage is off, the fan continues to operate within the set time period adjustable from 2 to 30
min by the timer.
To adjust the fan turn-on delay time, turn the control knob T clockwise to increase and counter-clockwise to decrease the
turn-on delay time respectively.
WARNING! The timer circuit is live! Disconnect the fan from power supply prior to any adjustment operations.
The fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments.
Use it to change the turn-off delay time and the humidity set point.
Do not use a metal screwdriver, knife, etc. for adjustment operations not to damage the circuit board.
The Stream ...U/Un fan is equipped with a TSC electronic module (speed controller with an electronic thermostat) for
automatic speed control (air flow) depending on the air temperature.
The terminal compartment incorporates 2 control knobs:
• presetting speed;
• setting electric thermostat threshold value.
This indicator lights when the air temperature exceeds the set value.
To set the thermostat threshold, rotate the thermostat control knob clockwise to increase or counter-clockwise to decrease
the temperature set point accordingly.
To set the fan speed (air capacity), rotate the speed control knob in the same way.
The fan operating logic may be based on temperature or timer indications:
As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the fan operates
with the set speed.
The Stream ...P fan is equipped with a speed controller that enables switching the fan on/off and smooth speed (air flow)
regulation from minimum to maximum value.
20
Stream EC
The EC motor is controlled by sending of an external control signal from 0 to 10 V to the X2 terminal block or by the R1
internal speed controller. Control method selection is carried out by means of the SW DIP switch:
• DIP switch in IN position. The control signal is set by the R1 internal speed controller that enables switching the fan on/off
and smooth speed (air flow) regulation from minimum to maximum value. Rotations are controlled from the minimum
(extreme right position) to the maximum (extreme left position). When rotating counter-clockwise, the rotations increase.
• DIP switch in EXT position. The control signal is set by the R2 external control unit.
DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT
OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD
